Squawk no more: Dolby, British Telecom aim to improve conference call audio quality

Dolby plans to sell an audioconferencing system on the strength of its Dolby Voice technology and its reputation for high-quality audio.

There's a reason why they call it a squawkbox. For years, users on audio-only conference calls have weathered annoying background noise, unexpected interruptions, and other problems. Dolby, whose name has become synonymous with high-quality audio, hopes to solve these with a new conferencing system.

Dolby announced the Dolby Voice Conference Phone, a $1,600 unit that, for now, will be the only device to incorporate its Dolby Voice technology to minimize some of the audio issues. Later this year, British Telecom (BT), will put its BT MeetMe name on its own Dolby-powered audioconferencing system, and add a Dolby-powered VOIP smartphone app to boot.

Dolby launched Dolby Voice last fall. A study the company commissioned showed that the technology was more effective than conventional calls at allowing users to hear and distinguish among words. "Otherwise, you get situations where people drone on and on," said Mike Fratesi, the director of integrated marketing at Dolby, in an interview. "You lose a lot of the subtle cues that take place in a face-to-face meeting," Fratesi said. 

Essentially, the Dolby phone plugs into the back end of an existing audioconferencing system, executives said, integrating with systems like the Cisco Unified Communications Manager. The conference phone weighs 3 pounds, and it includes a 4.3 in., 480-by-272-pixel  LCD for setting up calls.

What makes the Conference Phone special, according to Dolby, is that the system virtualizes the participant voice, projecting each voice in a separate virtual space around the table, so that users get a better idea of who's speaking. Otherwise, the audio capabilities include wideband HD audio (160 Hz to 14 kHz), a 20-foot mic pickup range, 360-degree audio capture, plus the expected full-duplex capability, with noise suppression and full echo cancellation.

The BT MeetMe with Dolby Voice mobile app for both the iPhone and Android platforms, moreover, allows users simply to "tap in" to a call, without the need to dial in with a PIN or other identification. The app also applies the Dolby Voice technologies to the mobile call, including ambient noise filtering and volume leveling. BT's technology will be undergoing live customer trials in the next few weeks, executives said.

"The Dolby Voice Conference Phone gives workers a full picture of what is happening on a conference call," Andrew Border, vice president of the Dolby Communications division, said. "Everyone knows who is speaking and understands what is being said."

Of course, vendors like Skype and others would argue that a videoconference would give the truest picture of what's being said on a call. But for now, streamlining the experience of dialing in to a call from a mobile phone is something that can never be improved too much.
